Following the introduction of the Ryzen 7000 series of "Zen 4" processors last month, AMD released a code patch that provides initial support for the GNU Compiler Collection (GCC) for Zen 4 CPUs.
But Zen 4 CPU support costing, tuning remains the same as znver3, with few patches for optimizations like instruction latency differences. As you can see from the patch, PTA_ZNVER3 is directly converted to PTA_ZNVER4 support.
Currently, the GCC support code for the base Znver4 is available on the mailing list , hopefully it will be included in the GCC 13 mainline, and then released around April next year.
The same week AMD released Zen 4 for GCC, Intel rolled out GCC patches for Meteor Lake and Sierra Forest . According to foreign media Phoronix , Intel usually adds compiler support for its new CPUs to GCC (and Clang) years in advance, especially when adding major ISAs.
